Can We Learn Something From the Small Plot INtensive (SPIN) Gardening Website?

I received the following question, which I believe may be of interest to some of you serious vegetable gardeners:

“I am looking at several options in gardening and hope you can
clarify something – I am mainly looking at the Mittleider and the
SPIN Farming processes. The two do not appear to be exclusive of each other but I know nothing of ether program (material ordered) so I am hoping you can provide any comparison/contrast if there is any and confirm if the two can be used in a single gardening system?”

I didn’t have much time to check it out, but I will do more later if
possible before leaving for Armenia and the Republic of Georgia, where we are working on two humanitarian projects.

It appears from the first glance that there are many areas of
compatibility, and that a person can learn much about marketing
crops from this website.

Two things I noted include

1) they use beds that are 2′ wide with 2′ aisles. This is not as
efficient as using narrower beds and wider aisles. Beds of 18″ –
tip of ridge to tip of ridge – which gives a 12″-wide planting area,
are ideal for plant spacing, feeding, weeding, and watering. Wider
aisles are also better. If you are growing smaller plants
exclusively you can use 2′ – or even narrower – aisles, but when you plant large plants, such as zucchini, and climbing plants, you need wider aisles to provide adequate space and light for the plants as they reach maturity. I suspect our plant spacing may be different (closer) than theirs also.

2) They also use only organic materials to feed their plants. This
certainly can work, but has drawbacks and hazards. Most manure and compost have not been sterilized, and therefore can have diseases, bugs, and weed seeds in it, which will flourish in your garden and substantially reduce your yield. Unless the organic material HAS been composted very efficiently in an aerobic process, which requires sustained temperatures of 140+ for several weeks, you get the aforementioned problems, plus you get much lower nutritional value.

And of course you do not know what or how much you are feeding your plants, since every batch of manure/compost is different, and
because none of them have been analyzed to determine their nutrient content. You can expect the manure to have much LESS nutrition than the original plant contained because of going through the cow, then sitting in a compost pile for months in the rain and snow.

Another problem with using organic materials – typically done one
time before planting – is that several inches of manure/compost
often contain much MORE mineral salts than are good for tiny young plants, and sometimes germination and growth are inhibited or the plants even killed with too much of a good thing. Then, in a couple of months, when large and ever-bearing plants need constant nutrition for producing several months of fruit harvest, the nutrition from the one-time-applied organic material is pretty much used up, and your plants stop producing – right when they should be really getting into it!

If you can learn and apply the growing procedures as demonstrated to be extremely successful in 32 countries around the world over the past 45 years, and use the marketing and other skills taught by these folks, you can have the best of both.
